Our team of dentists—Dr. Ron Ames, Dr. Lance Martin, and Dr. Jessica Prograis—combines decades of experience with a thoughtful, patient-first approach to care. While each dentist brings unique training and perspective, they share the same goal: helping individuals and families maintain healthy, comfortable smiles in a welcoming environment.
Preventive Care Designed for Comfort and Continuity
Preventive dental care forms the foundation of long-term oral health. Regular exams, professional cleanings, and routine monitoring allow issues to be addressed early—often before more complex treatment is needed.
